问题描述
我正在尝试在DevOps构建管道中构建.Net Core 3.0 (preview)项目.
I am attempting to build a .Net Core 3.0 (preview) project in a DevOps build pipeline.
azure-pipelines.yml中的步骤一直执行到"docker build"步骤，成功启动了构建过程.读取并执行Docker文件，直至执行"dotnet build"步骤，然后引发以下错误.
The steps in my azure-pipelines.yml executes up to the "docker build" step, successfully initiating the build process.The Docker file is read and executed up to the "dotnet build" step after which the following error is thrown.
我试图通过执行dotnet build".csproj" -c Release -o/app在本地进行构建然后，构建成功，错误为0，警告为0.这可能与DevOps中的SDK问题有关吗?
I have attempted to build locally by executing dotnet build ".csproj" -c Release -o /appThe build then succeeds with 0 errors and 0 warnings. Could this be related to an SDK issue in DevOps?
任何建议将不胜感激.
我的Docker文件中的build命令.
The build command from my Docker file.

推荐答案
在我的情况下，我不得不重命名项目文件夹，以使其与dockerfile中的项目本身不同:
in my case i had to rename the project folder to be different than the project itself in dockerfile:
FROM mcr.microsoft.com/dotnet/core/sdk:3.0 AS build
WORKDIR /src
COPY ["<project-name>.csproj", "<project-name>_build/"]
RUN dotnet restore "<project-name>_build/<project-name>.csproj"
